System and method for guided printer servicing

ABSTRACT

A guided barcode printer diagnostic and servicing system and method includes a software application for a smart phone that simplifies the process of detecting problems with and servicing a malfunctioning barcode printer. Illustrated, audible, and/or written instructions prompt the user to obtain photographs, video recordings, and/or audio samples of the malfunctioning printer. Data processing algorithms extract diagnostic data from the photographs, video recordings, and/or audio samples. The diagnostic data is compared to known printer problem data stored in a database. If a potential problem is identified, a likely repair solution is presented with easy-to-follow servicing instructions. If a potential problem is not identified, additional troubleshooting steps are performed by the user, if needed, until the barcode printer is fixed or it is determined that a skilled service technician is needed.

FIELD OF THE INVENTION

The present invention relates generally to a system that facilitates the troubleshooting and repair of printing equipment, and more specifically, to a system that provides guided servicing of barcode printers through automatic problem detection and clearly explained repair steps.

BACKGROUND

Barcode printers are specially designed printers designed to produce barcode labels. Barcode labels can be encoded with identification and other information and attached to countless items and objects. Barcode printers are ruggedly designed for long-term continuous use but like most devices with electro-mechanical rotating components, they eventually malfunction and stop operating as intended.

Periodic servicing and preventative maintenance procedures are often performed to ensure reliable operation of barcode printers. However, even well maintained printers may stop working due to the unexpected failure of individual components. These breakdowns often result in significant costs due to unscheduled down-time and costly repair bills from specialized printer repair technicians.

Businesses that rely on barcode printers often have service contracts with skilled technicians for periodic servicing and ‘as-needed’ repairs of their printers. Service contracts help ensure the availability of qualified repair technicians in the event that emergency repairs are needed. However, service fees may still be assessed even if no repairs are needed for a given period. Further, the cost of service calls may quickly add up and cut into profits depending on the nature, duration, complexity, and time of the calls. Still further, time spent waiting for a service technician may cut into profits even more if production is affected.

Therefore, a need exists for a guided printer servicing system that assists with troubleshooting common barcode printer problems to the extent that an end-user with limited repair skills or training may restore a malfunctioning barcode printer to full working order. A need further exists for such a guided servicing system to operate on a widely available mobile computer or other portable electronic device such as a smart phone.

DETAILED DESCRIPTION

The present invention embraces a system and method of providing guided printer servicing, i.e., troubleshooting, for, but not limited to, barcode printers. The system and method reduce the technical skill level needed to diagnose and repair malfunctioning printers as well as to perform routine servicing of normally functioning printers. In one embodiment, a software application (‘app’) running on a smart phone directs a user to obtain photographs, video recordings, and/or audio samples of a problematic barcode printer. The application performs various signal processing and diagnostic algorithms on the recordings to obtain diagnostic data. The diagnostic data is then referenced against a database containing information about known printer problems to identify one or more potential problems. After a potential problem is identified, a series of user-directed servicing instructions are presented via the smart phone.

The intelligence provided by computerized problem detection along with the easy-to-follow servicing instructions enable an end user, even one with limited technical aptitude or training, to successfully troubleshoot and service a problematic barcode printer. Costs associated with printer repair technicians would be significantly reduced because most barcode printer problems will be resolved faster and cheaper with on-site personnel. The present invention also provides preventative and predictive maintenance servicing on all printers by audibly detecting worn components that may be close to failing, causing unplanned downtime. Even skilled printer service technicians would benefit from the present invention by reducing the time and effort needed to detect and identify problems with a malfunctioning printer.

Referring now to the drawings, aspects of a preferred embodiment of a guided servicing system 100 for a barcode printer 101 of the present invention are illustrated. The functions described herein may be executed by a smart phone 102, implemented with computer executable instructions (i.e., smart phone application 103) which can be downloaded onto and operated by the smart phone 102.

The guided printer servicing system 100 may utilize standard features of the smart phone 102, such as an image capturing device (i.e., camera 106), a processor 108, and a memory unit 110. The system 100 further includes a diagnostic database 112 stored in the memory 110 that is populated with information on known barcode printer problems. The diagnostic database 112 also includes additional barcode printer-related information such as brand, model, parts list, troubleshooting instructions, and solutions (i.e., servicing instructions) matched to known printer problems. The known printer problem information may be derived from visual and audio data obtained during the printer development and testing phase and from historical repair data of different models of barcode printer 101. The diagnostic database 112 may receive updates with new printer problem and repair information periodically.

In one embodiment of the guided printer servicing system 100, the smart phone application 103 is initiated by selecting an associated icon (not shown) on the smart phone 102. The application 103 displays a series of troubleshooting instructions that may include asking a user to identify the type of printer 101. Alternatively, the user may be asked to take a photograph of the printer 101, which is then used by the application 103 to identify the printer through a spatial-recognition algorithm. The troubleshooting instructions are then presented in an easy-to-follow manner through words, audible instructions, animations, illustrations, or other self-evident graphics.

In accordance with the troubleshooting instructions, a first set of photographs, video recordings, and/or audio samples of the problematic barcode printer 101 are obtained using the servicing application 103 on the smart phone 102. The application 103 processes the images and recordings with various algorithms to derive ‘diagnostic data’ that is specific to the barcode printer 101 being serviced. The diagnostic data of the problematic barcode printer 101 is compared with known printer problem information stored in the diagnostic database 112. Based on pre-determined rules and criteria, the application 103 may or may not initially identify a potential problem from the diagnostic data.

If a potential problem is not identified, additional troubleshooting instructions directing the user to perform actions on various components 132 (e.g., removing certain rollers or lifting levers) are presented and new images and recordings are obtained. The new images and recordings are processed in the same manner to provide additional diagnostic data that is again used by the application 103 to attempt to identify a problem.

If a potential problem is identified, a likely solution, matched to the problem in the diagnostic database 112, is identified and a series of associated servicing instructions are presented through the smart phone 102. The servicing instructions are also prepared in an easy-to-follow manner with simple written phrases, animations, and other illustrative graphics.

Referring now specifically to FIG. 1, an exemplary embodiment of the guided printer servicing system 100 is illustrated. The guided servicing system 100 includes smart phone 102, processor 108, and memory 110 storing both the printer servicing application 103 and the diagnostic database 112. The present invention is not limited to any one device and the term ‘smart phone’ and ‘portable electronic device’ as used herein may encompass other mobile computer devices that have, or are in communication with, a camera, interactive display, processor, and memory. Examples of such devices include a tablet computer, laptop computer, handheld computer, portable scanner, or an augmented reality (AR) device.

The guided printer servicing system 100 further includes the camera 106 for obtaining photographic images and video recordings (i.e., sequential photographic images) of the barcode printer 101. The system 100 may also include a microphone 116 for obtaining audio samples of sounds made by moving components of the barcode printer 101 during a label printing operation. The system 100 further includes a pressure-sensitive user interface, i.e., touch screen display 118, to present information and receive input from the user.

Other standard features of the smart phone 102 such as a GPS unit 120, wireless communication unit 122, and network adapter 124 may also be utilized by the system 100. In the present embodiment, the features and functions of the smart phone 102 may be controlled by the printer servicing application 103 in accordance with the operating system 126.

In a typical servicing operation, the printer servicing application 103 displays a graphic representation 128 of the barcode printer 101 being serviced on the smart phone 102. The graphic representation 128 may be a graphic image or outline presented in a way to assist the user in obtaining a suitable photograph for the application 103. Illustrated in FIG. 1 is a typical troubleshooting step in which the user has been instructed to lift or raise a printer cover 130 to provide an unobstructed view of the internal components 132 of the printer 101.

The application 103, through various troubleshooting instructions, may direct the user to obtain a number of photographs of the printer 101 from one or more angles and distances. The representation 128 on the display 118 may be an actual image of the printer 101 or an illustration demonstrating one or more of the troubleshooting instructions needed to be performed by the user. The smart phone 102 may employ standard auto-focus techniques to set an initial image focus and can warn the user if the camera 106 is unable to achieve proper focus. A stereoscopic or Simultaneous Localization and Mapping (SLAM) algorithm may be used to create 3D imagery if multiple images have been taken from different perspectives. Computation of image derivatives and audio correction, if needed, can be performed by existing capabilities of the smart phone 102.

The guided printer servicing system 100 may obtain printer identification information (i.e., manufacturer, model, etc.) through a visual analysis process. In one embodiment, the application 103 uses an image recognition algorithm to determine the manufacturer and model of the barcode printer 101. Printer identification information may otherwise be obtained by scanning and decoding a barcode label (not shown) or alphanumeric characters affixed to the printer 101, receiving the information wirelessly, or by user entry with the smart phone 102.

After identifying the barcode printer 101, the application 103 accesses the printer-specific data including the parts list and troubleshooting instructions from the diagnostic database 112. As stated, the troubleshooting instructions are simple and presented in an easily understood manner. The troubleshooting instructions provide the steps needed to obtain suitable images and audio samples of the internal components 132 so that the application 103 may attempt to detect problems. Depending on the nature and location of the problem, multiple instructions may be needed to obtain images of the problematic components. The troubleshooting instructions may also include directions for the user to attempt to print a barcode label. While the barcode printer 101 is printing, or attempting to print, the label, photographs or video recordings may be obtained via the camera 106. Noises made by the printer components 132 may be recorded via the microphone 116. The images and audio samples are digitally saved to the memory 110 in an accepted file format.

Troubleshooting of the barcode printer 101 is automatic in the sense that the printer servicing application 103 performs all of the data analysis and problem determination while the user merely follows the troubleshooting instructions to move or manipulate components 132, print barcode labels, and obtain images and audio samples of the printer 101 using the smart phone 102.

The images and audio files of the printer 101 are processed using known image and noise algorithms to produce diagnostic data on the current state of the printer 101. The application 103 may implement one or more algorithms on the recorded images to provide data on the internal components 132 through spatial recognition, damage detection, and information extraction techniques. The application 103 may also implement one or more algorithms on the audio samples to provide diagnostic data through frequency-domain analysis, noise recognition techniques, or other known analytical methods.

After obtaining and processing the diagnostic data, the application 103 compares the data from the printer 101 with predetermined data with various levels, values, ranges, and amounts associated with known printer problems. Analysis of the visual images may enable the application 103 to detect problems that present visually such as worn rollers, misaligned or jammed label rolls, bent pins, stripped gears, and the like. Even problems with a circuit board 134 such as a loose connector 136 or a blown fuse may be detected through processing and analyzing the visual images. Diagnostic data derived from frequency analysis of the audio sample may provide information that allows for the application 103 to detect problems such as uneven roller wear or failing servo-motors that would not be detected by visual means alone.

If the application 103 does not determine a potential printer problem, the user is prompted to perform additional steps and obtain more specific or localized audio samples and visual recordings. The process may be repeated by instructing the user to remove additional internal components 132, all the way down to the circuit board level.

The servicing instructions, also stored in the diagnostic database 112, matched to the potential problem are then presented to the user. After completing the steps, the user is queried as to whether or not the problem has been resolved. Alternatively, a self-diagnostic test may be performed by the printer 101 and the status wirelessly sent to the smart phone 102.

As noted, the invention embraces a systems and method for providing guided servicing of barcode printers through simple user instructions to acquire diagnostic data in the form of images and sounds, automatic potential problem detection based on the diagnostic data, and simple user repair instructions based on likely solutions to the potential problems. The system 100 may provide individual and generalized servicing data and statistical information obtained during use of the application 103 in both resolved and unresolved printer troubleshooting by end-users. Such data and information may be used to improve the capability of the diagnostic database 112. New servicing scenarios could be developed and wrongly-identified root causes, i.e., printer problems, may be corrected through analysis of data obtained over time from countless uses of the troubleshooting application 103.

FIG. 2 is a block diagram depicting an exemplary method 200 of providing guided servicing of the barcode printer 101 according to the present invention. FIGS. 3-5 graphically depict sequences incorporating portions of the barcode printer servicing system 100 and method 200 of FIGS. 1 and 2.

The exemplary method 200 includes a data acquisition step 202 to obtain images and audio samples of a barcode printer 101 being serviced. Simple troubleshooting instructions are presented to the user via the smart phone 102. Screen graphics, written phrases, audio commands, or a combination thereof can be utilized to help a user understand the steps needed to obtain the images and audio samples.

As seen in FIG. 3A, troubleshooting steps including “lift printer cover” and “aim camera at printer media compartment” instructions 137 are communicated to the user via the display 118. An image 128 of the printer 101 is also shown on the touch screen display 118. The image 128 may be a photographic reproduction of the printer 101 or it may be an illustrated depiction of how the printer 101 should look after the instructions have been performed. The illustrated depiction 128 helps the user understand the steps needed to be taken by visualizing the process. As illustrated, the printer cover 130 is in a lifted position to provide an unobstructed view of the internal components 132. Without reading or even understanding the written instructions, a user would clearly understand what they were expected to do just by looking at the representation 128.

A graphic button 138 presented on the display screen 118 includes the self-explanatory instruction to “Take Photo”. The button 138 may be shaded and inoperable until the application 103 detects that the user has performed the requested instructions. At that point, the button 138 may become illuminated and operable so that the user is able to take a photograph as instructed.

As seen in FIG. 3B, additional troubleshooting steps presented to the user include “send print job to printer” and “record audio” instructions 137. A generated image of sound waves 131 is displayed on the screen 118 along with the button 138 and a self-explanatory label of “Record Audio”. As clearly indicated, the user is instructed to attempt to print a label and obtain an audio sample of the printer 101 in operation.

The exemplary method 200 also includes a data processing step 204 that occurs after the visual images and audio samples have been obtained and stored in memory 110. In this step, the image and audio files are processed with various algorithms to extract the diagnostic data in the manner previously discussed. Image processing algorithms characterize and quantify spatial features and other physical aspects of the printer 101. Audio processing algorithms analyze the different sounds and frequencies and attribute them to current conditions of printer components 132. The processing of the visual images and audio samples results in the capturing of information representative of known printer problems, i.e., the diagnostic data.

The exemplary method 200 further includes a data analysis step 206. Analysis of the diagnostic data may include detecting structural problems, characterizing functional issues, and determining potential operational problems. The diagnostic data is also compared to known printer problem data in the diagnostic database 112. If there is a sufficient match between the diagnostic data and that of a known printer problem, the application identifies the printer problem as a ‘potential problem’ with the particular barcode printer 101. At this point in the process, it is unknown if the ‘potential problem’ is an actual problem with the printer 101 but only that they share similar characteristics.

As shown in FIG. 3C, more than one potential problem may be identified for the barcode printer 101. A percentage likelihood may be listed with each potential problem depending on the similarities between the diagnostic data and known printer problem data. In the illustrated scenario, a potential problem of ‘Ribbon fitted wrongly’ is given a 95% likelihood of being the cause of the problems with the printer 101 while a potential problem of ‘Out of paper’ is only given a 5% likelihood of being a potential problem.

In Step 208, if no potential problem has been identified by the application 103, the process returns to the data acquisition step 202. Additional troubleshooting instructions are presented to the user, likely directed towards removing or manipulating additional internal components 132, and more images and audio samples are taken. The application 103 processes the additional images and sounds in step 204 to acquire more diagnostic data that is re-analyzed in step 206.

If a potential problem has been identified, the process includes presenting guided servicing instructions in step 210. The solutions to the potential problems are determined based on the proximity to a match in the diagnostic database 112. Pre-defined, clearly explained, and/or demonstrated user actions associated with the likely solution are presented on the smart phone 102 to the user. An exemplary guided servicing scenario is shown in FIGS. 4A-4C.

As seen in FIG. 4A, the application 103 presents a first repair steps to the user in both written form (“Lift lever” instruction 137) and with a graphic box 140 around the specific component to help the user understand the action that they are being instructed to do. After completing the action, the user presses the ‘Next’ action button 138 and the application 103 moves on to the next step. FIG. 4B includes a next step (“Pull out ribbon” instruction 137) along with a graphic box 140 surrounding the specific component 132 on the printer 101. After that action is completed, the user selects the “Next” action button 138 and eventually after completing all of the steps, is presented with the query screen shown in FIG. 4C. At the query screen, the user is presented with instructions 137 to send a label print command to the printer 101. If the problem has been resolved and the printer 101 appears to be functioning normally, the user is able to indicate this by selecting a “problem resolved” checkbox 142 and the guided printer servicing method 200 ends. If, after performing the actions, including those shown in FIGS. 4A and 4B, the printer problem is not resolved, the user may select a “problem not resolved” checkbox 142 and the guided printer servicing method 200 returns to step 202 to obtain additional diagnostic data and continue to attempt to resolve the problem.

FIGS. 5A-5C illustrate another scenario of with the printer guided servicing method 200. In this scenario, the barcode printer 101 has an electrical problem with the circuit board 134. In FIG. 5A, the method 200 is at the data acquisition step 202 and the application 103 has focused in on a potential problem with the circuit board 134. The user-directed instructions 137 in this scenario include “open printer cover” and “aim camera at circuit board”. A graphic representation 128 of the circuit board 134 is shown on the display 118. As in the scenario shown in FIG. 3A, the user is presented with the ‘Take Photo’ action button 138. The user may not be prompted to obtain an audio sample specific to the circuit board 134, although this may have already been done earlier in the guided printer servicing method 200.

The method 200 processes the data in step 204 and after referencing the diagnostic database 112 in analysis step 206, determines that there is a potential problem with the circuit board 134, specifically that a cable 144 is not properly fitted. In step 210, this potential problem is presented on the display 118 along with a graphic box 140 around the connector 136 as shown in FIG. 5B. In FIG. 5C, the display 118 shows a properly fitted cable 144 within the graphic box 140, both of which are intended to clearly instruct the user on the next step. The ‘Continue’ action button 138 becomes operable and when pressed, the method moves to step 212 where the application 103 may perform a diagnostic check to see if the printer 103 is operational or not.

In another aspect of the present invention, the barcode printer guided servicing system 100 can provide preventative maintenance analysis of operational barcode printers 101. As previously discussed, periodic analysis of audio samples may detect worn or otherwise problematic components that could fail prematurely, leading to significant repair and downtime costs. Repairs could be planned for scheduled downtimes. If the barcode printer 101 is determined to be in imminent danger of failing, emergency work requests and parts orders, if needed, may be generated.

While the specification described certain acts as being performed by the smart phone 103, it will be recognized that most processors could perform any of the aforementioned functions. The algorithms including those used to provide diagnostic data from the audio and visual recordings, as well as those used to detect and determine potential printer problems may be performed on the smart phone, at a central system, or distributed between various devices. Thus, the fact that an operation is described as being performed by the application 103 on the smart phone 102 should be understood as exemplary and not limiting.

The present technology can be used in connection with wearable computing systems, including head mounted devices (HMD). Such devices typically include one or more sensors (e.g., at least one microphone, camera, accelerometers, etc.), and display technology by which computer information can be viewed as overlaid on the scene in front of the user (also known as augmented reality (AR)).
